Valle d’Aosta dorm hostel?

Tentatively planning a solo ski trip to Valle d’Aosta after Chamonix. I have stayed at Chamonix Lodge before and it was great, dorms ~€30 with WiFi and common areas. Struggling to find info on dorm-style accommodation in Aosta, specifically to ski Monterosa. Anyone know of anything like this? Or any suggestions for something at another resort? I can’t be spending 100 euro a night on a hotel as I am only 1
